This invention describes a method for determining the relative effects of products on animal epithelial tissue. Also described is a method for evaluating quantitative changes on one or more affected surfaces of epithelial tissue of a subject caused by a test product. The methods of the present invention relate to the affect a product has on the epithelial tissue of a subject or the relative benefit of one product over another. In the first embodiment of the invention the products are test product, whereas in the second embodiment of the invention, the products are test products or comparison products. Products may be any product that may have an effect on epithelial tissue.

Non-limiting examples of such products include personal cleansing products, such as but not limited to: cosmetics, hair colorants, body wash, shampoo, conditioner, makeup, lotions, topical lotions, ointments, creams, skin lotions and the like; personal care objects, such as but not limited to: tooth brushes, hair brushes, brushes for a pet, and the like; clothing, such as but not limited to underwear, footwear and the like; medicaments; pet food; toothpaste; mouth wash; hand sanitizers; disposable absorbent articles, such as but not limited to, pads, tampons, training pants, diapers; hard surface cleaning compositions; facial tissues; wet wipes, such as but not limited to baby wipes, facial wipes, and the like; cleaning compositions, such as but not limited to dishwashing detergent, bleach, laundry detergent and the like; and combinations thereof.

Evaluating the pH and buffering capacity of moisture-containing cleansers
US Patent Application 20100197037
Publication Date: Aug. 5, 2010
Assignee: The Procter & Gamble Co. (Cincinnati, USA)

The present patent describes a system comprising a moisture-containing cleansing article and a visual pH indicator that changes changing color at a pH above 4.0. The system can comprise a buffer, having preferably a pKa above 5.5, and a set of instructions for evaluating moisture-containing cleansing articles. The pH buffer of the system can have a pKa value equal to or greater than the pH of the color change of the visual pH indicator. In addition, the pH of color change of the visual pH indicator can be equal to or greater than the pH of the lotion. This system can be used to evaluate the pH of moisture-containing cleansing article lotions and to quantify the ability to neutralize alkalinity such as the alkalinity provided by residues of feces and urine over time on the skin of a baby.
